## Abstract

An apparatus receives environmental data indicative of environmental parameters in a vicinity of a smart tray bearing a product thereon. The apparatus receives from the smart tray, network data being transmitted to the product via a network port in the smart tray. At least one outlier in the environmental data or the network data is identified. An action to be executed at the smart tray is determined in response to identifying the outlier.

## Claims

### Claim 1

A method of monitoring a product build process via a smart tray, the method comprising:
receiving from at least one sensor on a smart tray, environmental data indicative of at least one environmental parameter in a vicinity of a product being built;
receiving from the smart tray, network data transmitted to the product being built during the product build process via a network port in the smart tray, the network data including firmware or software loaded into the product being built;
identifying at least one outlier in the environmental data;
analyzing the network data, the analyzing including comparing a checksum of the network data to a trusted checksum, and including an authentication failure of the network data in the at least one outlier in response to the checksum not matching the trusted checksum;
determining an action to be executed at the smart tray in response to the outlier; and
transmitting the action to the smart tray to instruct the smart tray to perform the action affecting the product build process.

### Claim 2 (depends on 1)

The method of claim 1, wherein receiving the environmental data further comprises:
receiving the environmental data at a computing system remote from a manufacturing location of the product being built; and
comparing the at least one outlier to a corresponding predetermined threshold if the at least one outlier is identified in the environmental data.

### Claim 3 (depends on 2)

The method of claim 2, wherein determining the action is based on the comparison and includes determining that, in response to the at least one outlier being outside a specified range of the predetermined threshold, the action is to transmit a notification regarding the at least one outlier to a client device.

### Claim 4 (depends on 2)

The method of claim 2, wherein determining the action is based on the comparison and includes determining, in response to the at least one outlier being outside a specified range of the predetermined threshold, that the action includes transmitting a notification regarding the at least one outlier to a client device and instructing the smart tray to terminate the product build process.

### Claim 5 (depends on 1)

The method of claim 1, wherein receiving the environmental data from the at least one sensor further comprises:
receiving the environmental data from a plurality of sensors on the smart tray.

### Claim 6 (depends on 1)

The method of claim 1, wherein determining the action to be executed at the smart tray in response to the outlier further comprises:
determining, in response to the authentication failure being included in the at least one outlier, that the action includes transmitting a notification regarding the at least one outlier to a client device and instructing the smart tray to terminate the product build process.

### Claim 7 (depends on 1)

The method of claim 1, further comprising:
analyzing the environmental data and the network data to detect a correlation between the environmental data and the network data; and
generating a notification in response to detecting the correlation.

### Claim 8

A non-transitory, processor-readable storage medium storing machine readable instructions that when executed by a processor, cause the processor to:
receive environmental data indicative of environmental parameters in a vicinity of a smart tray bearing a unit under test (UUT) thereon;
receive from the smart tray, network data transmitted to the UUT via a network port in the smart tray, wherein the network data includes firmware or software loaded into the UUT;
analyze the network data, the analyzing including comparing a checksum of the network data to a trusted checksum, and determining an authentication failure of the network data in response to the checksum not matching the trusted checksum;
identify an outlier in the environmental data or the network data, wherein the outlier includes the authentication failure if analyzing the network data determines the authentication failure;
determine an action to be executed at the smart tray in response to the outlier; and
transmit the action to the smart tray to instruct the smart tray to perform the action affecting a test of the UUT.

### Claim 9 (depends on 8)

The non-transitory, processor-readable storage medium of claim 8, wherein the machine readable instructions further comprise instructions that cause the processor to: receive the environmental data from at least one sensor affixed to the smart tray.

### Claim 10 (depends on 8)

The non-transitory, processor-readable storage medium of claim 8, wherein the machine readable instructions to determine the action further comprise instructions that cause the processor to:
determine that a test of the UUT is to be terminated, and
determine that the action includes instructing the smart tray to terminate the est of the UUT.

### Claim 11 (depends on 10)

The non-transitory, processor-readable storage medium of claim 10, further comprising instructions that cause the processor to:
transmit a signal to the smart tray terminating the test of the UUT.

### Claim 12

An apparatus that monitors a build process, the apparatus comprising:
a tray configured to bear thereon a unit under test (UUT);
at least one sensor included in the tray that senses at least one environmental parameter in a vicinity of the tray;
a first network port included in the tray connectable to a factory network to receive data from the factory network;
a second network port included in the tray connectable to the UUT to convey the data received by the first network port to the UUT, wherein the data includes firmware or software to be loaded into the UUT;
a wireless transceiver included in the tray that exchanges data signals between the tray and a remote analytics platform via a wireless access point; and
a computing system incorporated into the tray, wherein the computing system transmits the at least one environmental parameter and the data to a remote analytics platform via the wireless transceiver and receives instructions from the remote analytics platform to perform an action when the remote analytics platform identifies an outlier in the at least one environmental parameter or the data, wherein the remote analytics platform identifies the outlier in the data by determining that a checksum of the data does not match a trusted checksum.

### Claim 13 (depends on 12)

The apparatus of claim 12, wherein the tray further comprises:
a backup battery that powers at least one the sensor, the wireless transceiver, and the computing system.
